In one desirable arrarigerhnh'the bodycomj fprises 'in' its base orfloor section a plurality of longitudinally-extending hollow frame members, shown arranged along the sides of the body. Air

is taken into these members, preferably through a novel cleaning device arranged adjacent and between these side members between the floor and bottom platesof the floor section, and is discharged into the body through openings adjacent the tops of the hollow side members.

One feature of the invention relates to heating or cooling the air so introduced into the body, to control its temperature. w

Many of the advantages of the invention can be secured by causing circulation of the air by means of openings at the top of the body which communicate with the exterior of the body at a point where there is a low pressure area when the vehicle is in motion. However, one of the principal features of the'invention relatesto the use of engine-driven means for positively'circulating'the air. a a

The automobile-illustrated diagrammatically in Figure 1 includes a body I 0, the flo'orsection of which is reinforced to form a substitute for the usual frame as fully described in my application No. 718,929,- filed April '4, 1934, now Patent No.

' 2,100,561, patented NOV. 30, 1937, and which has an engine I! arranged under a hood it. The engine may be, and is shown as being, of the con-.

' struction described in my application No. 139,622, filed August 13, 1934. The engine is shown arranged behind a radiator .18 inthe front end of thehOOd.'- .7 i 1 The floor section of the body is" formed of vertically-spaced horizontal floor and bottom plates 7 II and 20 (Figures 2 and 3l enlbracing-suitable' air-cleaning devices suchlas bones lt zcontaining'metal floss or other cleaningmaterial; Air enters the bottom of the, cleaning} 28, through suitable louvered openingsis'in bottom 'plates' 2' (Figures 3 and of --the bottom plates 20 may be madereadiiyfremov- 5 acilitate' replacement of: the r l bureter. 1 H v v I I I Aetgokrdmg to 18 a devices a en beneath en rom v v n t v v. teringthroughth h u m .an enclosure whi ,thegenerator and n unnamed bevheatedmlthe ln bv. v, the-mandamus hollow members; shown i 'lcure '4, the intake end' ofthe pipes at is connected-tome water jacket of the engine, iorlekample through a suitable valve 3;, which controls a conduit 34' serving as a-water return tothe radiator ll.

.'1he" valve 32 may be water "from the, pipes ll and'send it alljthrough the ",or it maybe set to divert of t water pipes", shown arranged in set team on the itintothepipesll."1hereturnendofthe pipesllisshownconnectedtoawaterpump a which circulata the returned water, as well as cooled water from a conduit 38 from the radiator, through a perforated pipe 40 which sprays the cooled water into the uppermost part of the water jacket, above the engine cylinders.

As explained in my said application No. 789,622, normally the engine is cooled by the circulation of water sprayed into the jacket by pipe II and returned to the radiator through conduit 34. If, however, the engine temperature rises too high, some steam is formed, and this steam escapes through a conduit 42 which conducts it .to the radiator it, where it condenses. If desired, part of the steam space in the upper part of the water jacket may be protected from the s ray from pipe SI, and steam withdrawn therefr to circulate through the pipes ll instead of hot water.

In the summer, the air entering the body may, if desired, be cooled by passing it through boxes 44 containing ice or solid carbon dioxide or other refrigerant. As shown in Figure 3, when this is done a suitable valve 46 is operated so that the cleaned air is discharged from the cleaner 28 into the cooler 44 instead of directly into the member 24.

Figure 8 shows diagrammatically this arrangement for cooling. With the valve 48 in the position shown the air passes from the cleaner 2! through the dry ice in and thence into the hollow member 24. By shifting the valve 48 downwardly into a vertical position, the air passes directly into the, hollow member 24 from the air cleaner.

Many of the advantages of the invention can be I secured, as shown in Figure], by causing aircirculation through the body by means such as air conduits l5. concealed in the roof, and having openings communicating with the space in the upper part of the body, and which open on the outside of the body at a point where there is a low pressure area when the vehicle is in motion. In the arrangement shown in Figure 5, this outside opening is at "52. just above the rear window and just below the point at which the roof merges into the rear of the car body. At this point there is normally such a low pressure area when the vehicle is in motion. Suitable valves or shutters may be provided for conduits I" to control the air circulation.

I prefer, however, to provide engine operated means for positively circulating the air. As shown in Figures 1, -2, 4 and 7, conduits 5| concealed in the roof, and having openings communicating with the interior of the body, may be led down the front door post I at one side of the windshield as shown in Figure 7, and connected to an air mixing or control device 54 through a suitable conduit 55. The conduit 50 may be directly connected to the control device 54 as shown in Figure 1. If preferred, the conduit ill may open into a hollow vertical support such as the hollow door post 5i which may be arranged to open into a hollow closed off air-box 53 formed at the front end of one of the side members 24,

erably comprises a valve or shutter 58, operable by the driver from within the body by means of a Bowden'oontrol II or the like having its end mounted on the instrument'board II.

The valve I! can thus be set in different positions, to proportion the air taken from conduits II and that taken in from the space under the hood through louvered openings I2.

'Iheairsotakenintothedevicellpasses through an opening it into the top of a cover ll mounted on the top of the engine. ,I'henoe it passes down through an air cleaner Cl, and circulates over the spark 131 18 and other parts mounted on the top of the cylinder head, to aid in keeping them cool. Thence it is conducted, by suitable conduits, to the air intake of the engine carbureter (not shown). Thus the engine suction is utilized to cause a positive circulation of air through the body.

Figure 7 also illustrates an alternative construction, according to which the bottom plate 20 is replaced by two side plates in and an. inter,-

' a starter indicated diagrammatically at ll. The

air may here be additionally cleaned by passing through cleaning material I". The air is taken in through louvered openings 82, which may open to the space alongside the engine or, if preferred may open downwardly into the crankcase.

In this case, the air passes from valve I54 into the cover I", where it first passes through the cleaner Cl and then sweeps forwardly the whole length of the engine into a conduit III which curves rearwardly from the front end of cover I 86 to connect with the air intake of a downdraft carbureter l2.- 1

While illustrative constructions have been described in detail, it is not my intention to limit the scope of the invention to those particular constructions, or otherwise than by the terms of the appended claims.
